System of Super-Earths Discovered Around A Nearby Star

If you look up at Earth’s night sky and find the constellation Cetus — it looks something like a sea monster — you might also notice a rather average looking star called Tau Ceti. It’s slightly smaller than our sun and sits just 12 light years from Earth.
